Widget - input/ProductCategoryInput - filter

Content

Hi,

Im using this widget:

<rn:widget path="input/ProductCategoryInput" name="Incident.Product" required_lvl="1"/>

On page we see all Products

How to set this widget to show only Product numbers I want?

I'm Trying to do this:

<rn:widget path="input/ProductCategoryInput" name="Incident.Product"  default_value="161,163" /> 

Show only 161+163 

but this is not working,

we can see them all.

Please assist.

Thanks, Gil.
